I have an AsRock H61M-DGS motherboard that takes up three slots; are there any computer cases out there that have the same? I can only find ones with two slots or four. I know that the motherboard is technically mini ATX, as mentioned in the description, but a mini ITX that happens to have an extra slot would work as well. My goal here is for it to be as compact as possible, but without using half-height PCI slots.
